Network requirements
As shown in
Figure 7
, Device A is connected to GigabitEthernet 1/0/1 of Device C, Device B is
connected to GigabitEthernet 1/0/2 of Device C, and the packets from Device A and Device B to Device
C are not VLAN tagged.
Make configurations to have Device C preferentially process packets from Device A to Server when
GigabitEthernet 1/0/3 of Device C is congested.
